If you have pages or documents which contain tables these options help you to make the most of them. They are especially valuable in cases where you want to export the information contained in the tables to another Windows application.
The option 'Define cells of table according to lines' 'tells' the OCR software that only cells with borders should be recognized. If the internal OCR does not recognize a table properly just take the original page, draw lines where you want to have them, scan the page again and have it recognized once more. In 99.9 % of all cases this will do the trick.
The option 'Tables does not contain overlapping cells' ensures that no cell extends over another. If your table shows titles that go over more than one column this option should be turned off.
The option 'Cells contain exactly one row' means that all cells are recognized as having one line although borders or spacing may be missing.
